We investigate the possibility of designing machine learning models that can be accommodated entirely on quantum devices without the help of classical computers. With Dissipative Quantum Neural Networks, we simulate a quantum feed-forward neural network for denoising: the Quantum Autoencoder. We assign it to correct bit-flip noise in states that can exist only quantum mechanically, namely the highly entangled GHZ-states. The numerical simulations report that the QAE can recover the target states up to some tolerance threshold on the noise intensity. To understand the limitations, we investigate the mechanisms behind the completion of the denoising task with quantum entropy measures. The observationsreveal that the latent representation is key to reconstructing the desired state in the outputs. Consequently, we propose an inexpensive modification of the original QAE: the brain box-enhanced QAE. The addition of complexity in the intermediate layers of the network maximizes the robustness of the QAE in a setting where only a finite-size training data set is available. We close the argument with a discussion on the generalization properties of the network. 000941218 536__ $$0G:(DE-HGF)POF4-5224$$a5224 - Quantum Networking (POF4-522)$$cPOF4-522$$fPOF IV$$x0 000941218 8564_ $$uhttps://juser.fz-juelich.de/record/941218/files/Information_82.pdf$$yOpenAccess 000941218 909CO $$ooai:juser.fz-juelich.de:941218$$pdnbdelivery$$pVDB$$pdriver$$purn$$popen_access$$popenaire 000941218 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000941218 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000941218 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)188287$$aForschungszentrum Jülich$$b0$$kFZJ 000941218 9131_ $$0G:(DE-HGF)POF4-522$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5224$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Computing$$x0 000941218 9141_ $$y2022 000941218 920__ $$lyes 000941218 9201_ $$0I:(DE-Juel1)PGI-2-20110106$$kPGI-2$$lTheoretische Nanoelektronik$$x0 000941218 9201_ $$0I:(DE-Juel1)IAS-3-20090406$$kIAS-3$$lTheoretische Nanoelektronik$$x1 000941218 980__ $$amaster 000941218 980__ $$aVDB 000941218 980__ $$aUNRESTRICTED 000941218 980__ $$abook 000941218 980__ $$aI:(DE-Juel1)PGI-2-20110106 000941218 980__ $$aI:(DE-Juel1)IAS-3-20090406 000941218 9801_ $$aFullTexts
